"By means of the double-cross system we actively ran and controlled the German espionage system in this country." This extraordinary claim is made in this British top secret intelligence report written by an Oxford don at the end of World War II. The Masterman Report, now made available for the first time, with the permission of Her Majesty{u2019}s Government, describes the double-cross system and offers an account of its workings which clearly substantiates the claim.

A World of its Own is a sustained lyric, an enchanted and enchanting song that captures in words and colour the simplicity, the beauty, the aloneness of a little-known, unspoilt world. Poet and painter viewed this world with independent eyes, neither seeking to interpret for the other. In an unusual collaboration they have captured a subtlety of impression and recreated a wholeness of experience difficult for either to achieve alone. The poems have a rare visual quality about them and the paintings and sketches a lyrical eloquence as though each art was about to spill over into the other.

This book is the result of a life-long ambition of the author's to present a version of Marlowe's famous play Dr Faustus which has come down to us in a badly mutilated form. Marlowe died shortly after it was written and successive producers replaced much of his text with scenes of knock-about farce. Enough indications of the original form of the play remain, in the opinion of A. D. Hope, to enable a tentative restoration.

Papua New Guinea is on the verge of political independence and this volume gives important insights into the way its inhabitants are dealing with the new political institutions that have impinged upon them in the last years of colonial rule. The title suggests both the scope of the book and its main theme: it is not a study of a single village but of a district; and recent developments have widened the political horizons of its inhabitants in interesting ways.

The first publicised incursion of the Soviet Navy into the Indian Ocean was as recent as March-April 1968, though this was not the first time Soviet ships had entered the Ocean. The strength of the fleet is difficult to determine with any accuracy, but it is not such as to 'add up to a vast Soviet fleet cruising hungrily round the ocean.' Nonetheless, it does represent a new factor in the strategic situation in the region.

About one-third of the earth's land surface is desert. Yet, despite a large and varied literature, Desert Landforms is the first book arranged around landforms rather than geomorphic processes. A reeurrent theme is that desert landforms occur in assemblages that are profoundly influenced by geology and major relief. Accordingly, landforms are discussed within a number of fractional groupings in a downslope sequence of settings, ranging from desert upland to plain, an approach influenced by the author's experience in mapping such landform groupings in arid Australia.
